we calibrate HPLC once in 6 months while iam doing
calibration i came to know that calibration was failed.
then how can i justify that the samples analyzed on the
system during this 6 months was wright? how can i forward in
to the next step for those batches?

Answer Posted / ravi narwade

system suitability test for it, and if the "SST" is passing
no one will raise the question on analysis of samples on
the instrument which fails in calibration.
